| | Silanol Terminated Polydimethylsiloxane Usage And Synthesis |
| Chemical Properties | Silanol Terminated Polydimethylsiloxane is a silicon-basedorganic polymer that is nontoxic, optically clear, inert, and inflammablematerial. It is widely used in heat-resistant lubricants, fire retardants,medical devices, and cosmetics. Polydimethylsiloxane is hydrophobic,cytocompatible, and viscoelastic which can be used to prepare water-repellentcoatings in the textile industry. | | Uses | Polydimethylsiloxane is frequently used in a liquid containing 4-5% silica gel, emulsifiers and preservatives. It is employed in applications like contact lenses, medical devices, elastomers, in shampoos, food (antifoaming agent), caulking, lubricants, kinetic sand , and heat-resistant tiles. PDMS is a common surfactant, component of defoamers and as an herbicidal penetran. |
